5. The 7th grade has 386 students. There are 32 more girls than boys in the grade.
timama [110]

Answer:

161 boys

Step-by-step explanation:

First you find the even amount of boys and girls out of 386

386 divided by 2 = 193

Then you subtract 32 boys and add the 32 to girls since there are 32 more girls than boys

(boys) 193 - 32 = 161

(girls) 193 + 32 = 225

So there are 161 boys and 225 girls
